old mate

Yeah i have an 04 CRF450R, not EFI or anything but it's brilliant as it is. I still want more power though

Hey mate, i'm down in Narre Warren South yourself?

Yeaaah he did it back in the day though, about 20+ years ago haha. He was a total crazy dude, like the big 600HP torana and ****, or something around there. It's unbelievable. Do you ride yourself?

Hey buddy its well worth doing. at 100ks it revers just over 2500. A manual with 19s wheels is fine for 3.89. If you do alot of highway miles i would suggest 3.7. But if you want low down torque go 3.89
